Approximate Noether Symmetries of the Geodesic Equations for the Charged-Kerr Spacetime and Rescaling of Energy
Ibrar Hussain, F. M. Mahomed, Asghar Qadir
Using approximate symmetry methods for differential equations we have investigated the exact and approximate symmetries of a Lagrangian for the geodesic equations in the Kerr space…
Approximate Symmetries of Lagrangians for Plane Symmetric Gravitational Wave-Like Spacetimes
Ibrar Hussain, Asghar Qadir
Using Lie symmetry methods for differential equations we have investigated the symmetries of a Lagrangian for a plane symmetric static spacetime. Perturbing this Lagrangian we expl…
Weyl collineations that are not curvature collineations
Ibrar Hussain, Asghar Qadir, K. Saifullah
Though the Weyl tensor is a linear combination of the curvature tensor, Ricci tensor and Ricci scalar, it does not have all and only the Lie symmetries of these tensors since it is…
Second-Order Approximate Symmetries of the Geodesic Equations for the Reissner-Nordström Metric and Re-Scaling of Energy of a Test Particle
Ibrar Hussain, Fazal M. Mahomed, Asghar Qadir
Following the use of approximate symmetries for the Schwarzschild spacetime by A.H. Kara, F.M. Mahomed and A. Qadir (Nonlinear Dynam., to appear), we have investigated the exact an…
